Control range limitation of VSD
Basic unit could not correct the difference in speed and reached
a control range
limit. 1.
Basic unit is not standardized for this motor
repeat standardization.
!
Caution! Settings of air
-fuel ratio control must be
checked!
2.
Ramp time settings of the VSD are not shorter than those of the basic unit (parameters 522, 523) or the setting for the modulating operating
ramp is
incorrect (parameter 544)
3.
Characteristic of the VSD is not linear. Configuration of the volt
age input at
the VSD must accord with that of the basic unit (parameter 645).
4.
VSD does not follow quickly enough the changes of the basic unit. Check settings of the VSD (input filter, slippage compensation, hiding d
ifferent
speeds
1
Control range limitation at the bottom
VSD speed was too high
2
Control range limitation at the top
VSD speed was too low
81
1
Interrupt limitation speed input
Too much electromagnetic interference on the sensor line
improve EMC

#
Error during VSD’s speed standardization
1
Timeout of standardization (VSD ramp down time too long)
Timeout at the end of standardization during ramp down of the VS
D
ramp
time settings of the VSD are not shorter than those of the basic unit (parameter: 523)
2
Storage of standardized speed not successful
Error during storage of the standardized speed
lock the basic unit, then reset it and repeat the standardization
3
Line interruption speed sensor
Basic unit receives no pulses from the speed sensor: 1. Motor does not turn. 2. Speed sensor is not connected. 3.
Speed sensor is not activated by the sensor disk (check distance)
4
Speed variation / VSD ramp up time too long / speed below minimum limit for standardization
Motor has not reached a stable speed after ramp up. 1.
Ramp time settings of the VSD are not shorter than those of the basic unit (parameters 522, 523).
2.
Characteristic of the VSD is not linear. Configuration of the volt
age input at
the VSD must accord with that of the basic unit (parameter 645).
3.
VSD does not follow quickly enough the changes of the basic unit. Check settings of the VSD (input filter, slippage compensation, hiding d
ifferent
speeds)
4.
Speed of VSD lies below the minimum for standardization (650 1/min)
